Modern House Construction runs full remodels out of Marlborough, Massachusetts, and the name that keeps showing up in review after review is Udson, the owner, often working the job himself alongside a partner named Rodrigo. On Google the company holds a perfect 5.0 from 13 ratings, and Thumbtack — with by far its deepest review history — puts it at 4.7 from 49 ratings, 90% of them five stars. Thumbtack also lists a Massachusetts Construction Supervisor license for Udson Amorim, verified through its own background check.
The work described isn't small stuff. In an October 2025 review, a homeowner described gutting a 2,200-square-foot basement with no electrical, plumbing, or HVAC and coming out the other side with a theater, game room, gym, bedroom, and full bath. In a 2025 review, another homeowner described a major renovation that added a bathroom, redid two existing ones, installed cabinets and sliding doors, and built a closet — and when an issue turned up afterward, Udson sent his team back at no charge under the guarantee. A March 2026 review recounts an even bigger job, stripping a house down to the studs and rebuilding from scratch. Recent reviews keep circling back to the same two things: direct communication and fair pricing from Udson and Rodrigo themselves, and a company that shows up for kitchens, bathrooms, decks, and additions alike. Of the last 13 reviews in six months, none is negative.
The record isn't spotless further back. In a 2025 review on Angi, a homeowner who spent $115,000 on a 1975 mobile home renovation described months of delays, a siding color mistake, and workmanship issues. In a 2023 review on HomeAdvisor, a customer described a dispute over pricing for a two-door installation job. The company's BBB page carries a C grade and no accreditation, citing one complaint it didn't respond to along with its relatively short time in business.
The ratings themselves don't agree: Google, Thumbtack, and Angi all land between 4.3 and 5.0, while HomeAdvisor's two reviews average 2.8.
For a homeowner planning a real renovation — a basement, an addition, a full gut job — this is a company with a track record of finishing big, complicated projects and standing behind them afterward. Given the two older complaints about cost and schedule on larger jobs, it's worth nailing down the contract price, change-order process, and timeline in writing before work starts.
